Clemz Vinted extension: 2026 review and Bleam comparison
Clemz is a Chrome extension that automates tasks on Vinted. Bleam, which I built after 7 years of selling on Vinted, puts everything in one place: an AI assistant that replies to buyers and negotiates within the margin you set, 24/7 with Bleam Cloud, relisting, one inbox for all your accounts and an iPhone and Android app. Here's the point-by-point comparison, based on Clemz's public offering as checked on October 20, 2026.

Why this article
I've been selling on Vinted for 7 years with my company. Before creating Bleam, I tested most of the extensions out there, including Clemz. Today people often ask me: "I'm hesitating between Clemz and Bleam, which one should I pick?"
Rather than another marketing comparison, I'll honestly explain what each one does, where the real difference is, and which seller profile it fits. No bullshit, just my take as a reseller who uses these tools daily.
What Clemz actually is
Clemz is a Chrome extension for Vinted, on the market for several years. Comparison below based on Clemz's public offering as checked on October 20, 2026.
Clemz lets you repost your items, send messages to users who favorited your items, exchange views/favorites with other sellers, bulk-edit listings, automatically negotiate incoming offers with price rules, group your shipping labels and track your sales (invoices on higher plans).
Why I built Bleam
But as a high-volume reseller, I eventually hit the limits. Listing templates, hourly automatic backup, a conversational AI assistant — those were features I wanted and that the tools back then didn't offer.
I figured: if it doesn't work for me, there are probably plenty of resellers in the same situation. With a dev background, I jumped in. My cofounder and I built Bleam starting from our real reseller needs — not a theoretical spec sheet.
The result: every Bleam feature is pushed to the max, because we use the extension ourselves daily on our own accounts. When something bothers us, we fix it. That's the difference you'll see in the comparison in this article.
Bleam vs Clemz: the comparison table
The eight criteria that matter, side by side. On every line Bleam goes further: an AI that replies to buyers on top of negotiating, the inbox of all your accounts, a real iPhone and Android app, and everything keeps running with your computer off through Bleam Cloud.

What's new in Bleam in 2026
Bleam already put everything in one place. This year it goes even further:
- Centralized inbox: the Vinted conversations of all your accounts in a single inbox. You reply and send offers without opening Vinted, from any device.
- Wardrobe: your live Vinted wardrobe, all accounts together: repost, change a price or delete a listing, even from your phone.
- iPhone and Android app: your sales, your messages and a notification for every sale, wherever you are.
- Assistant Memory: teach it an answer for a category, a brand or an item, and it reuses it in every conversation.
- Lifecycle: an item isn't selling? Bleam lowers its price step by step down to your floor and reposts it.
- MCP connector: connect Bleam to Claude or ChatGPT and ask questions about your real numbers.
- Labels and SKUs: shipping labels for every Vinted country in A5 format, and the SKUs of a lot generated in one click.
What our numbers show
Before going feature by feature, here is what our sellers' sales say about negotiation and favorites (Bleam study, aggregated and anonymised data, August to October 2026):
- 75% of single-item sales close below the listed price, with a median discount of 18.1% (198,697 sales from August 21 to October 20, 2026). Reposting is not enough: the sale is made in the conversation.
- Buyers who propose a price ask for a median 27.8% discount, and the sale closes 12.8% below the listed price when the assistant counter-offers (118,698 proposals from August 21 to October 13, 2026).
- To favorites, a 10 to 15% offer yields 25.7 sales per 1,000 messages against 16.9 with no offer, 52% more; an offer under 10% changes nothing (478,885 messages from September 29 to October 12, 2026).

Messages to favorites
- ClemzPartial
- Clemz lets you send an automatic message with a discount to users who favorite your items. You can store up to 10 texts drawn at random and scale the discount by price range, but the text sent doesn't depend on the time, the day or the item price (documentation checked on October 20, 2026).
- BleamYes
- With Bleam, you can personalize the message with the buyer's username, and more importantly send different messages based on time of day, day of the week, or item price. A buyer who likes a €10 item Monday morning won't get the same message as a buyer who likes an €80 item Saturday night.
Listing templates
- ClemzNo
- Clemz doesn't advertise any listing template system (site checked on October 20, 2026).
- BleamYes
- With Bleam, you create reusable listing templates. When you have several similar items to post (same brand, category, size), you apply the template in one click and the listing fills itself. For resellers who post a lot, it's a massive time saver. Honestly, this was THE feature I missed most before building Bleam.
Reposting
- ClemzYes
- Clemz lets you repost your items, with a monthly quota depending on plan.
- BleamYes
- Bleam goes much further. Repost your whole closet in one click, or schedule reposts in advance (great to auto-repost over a weekend when you're away). Options for price change during repost (fixed, percentage, amount) and AI rewriting of title/description so each repost stays unique. With Lifecycle, Bleam even lowers the price of items that aren't selling on its own, step by step down to your floor.
Shipping labels
- ClemzPartial
- Clemz generates and groups the labels already available on Vinted (up to 50 per PDF, thermal format included) and also sends automatic after-sale messages, but it doesn't trigger the label order at the sale (documentation checked on October 20, 2026).
- BleamYes
- With Bleam, as soon as a sale is confirmed, the label is ordered automatically. Nothing to fetch, everything happens in the background. Auto-resizing for 4x6 thermal printers included. Add automatic post-sale messages (thanks after payment, review request after finalization) and your customer relationship runs itself.
Automatic backup
- ClemzPartial
- Clemz offers a backup system, but it's manual: you have to trigger it every time.
- BleamYes
- With Bleam, every listing in your closet is backed up automatically every hour (title, photos, description, brand, size, price, colors, category, full attributes). Huge benefit: if your Vinted account gets restricted or banned, you can restore your entire catalog on a new account in minutes. Real safety net, and imo it's non-negotiable when you live off reselling.
Multi-account Vinted
- ClemzYes
- Clemz includes a number of Vinted closets that depends on the plan, up to 10, with no shared inbox across accounts (checked on October 20, 2026).
- BleamYes
- With Bleam, you can connect up to 35 Vinted accounts on a single subscription. Everything managed from one Bleam space, with the inbox of all your accounts, and every automation runs in parallel on each account. For resellers with 2, 3, 5+ accounts, it's a real time saver.
AI assistant
- ClemzNo
- Clemz automatically negotiates incoming offers with rules (minimum price, stepped counter-offers), but has no AI assistant answering buyers' questions: its "AI replies" are announced as "coming soon" (documentation checked on October 20, 2026).
- BleamYes
- With Bleam, you can enable an AI assistant that negotiates prices based on your set margins and automatically replies to buyer questions. It runs while your browser is open, or 24/7 with the Bleam Cloud add-on: while you sleep, while you work, while you're doing anything else, it sells for you. You keep full control of the rules (margins, counter-offers, acceptance message, floor price).
Bleam Cloud (optional)
- ClemzNo
- Clemz requires your browser to be open to run.
- BleamOptional
- With Bleam Cloud, your extension runs on a dedicated server managed by us. Even when your computer is off, Bleam keeps replying, reposting, sending favorite messages and negotiating. For real pro resellers, it's a game changer.
Who should pick what
Here's my simple rule, based on what you sell per month.
Beginner or casual seller (under €1,000/month)
Bleam. You get automatic and scheduled reposting, favorite messages, listing templates, one-click labels and hourly automatic backup. You save time from day one, with a 14-day free trial.
Regular seller doing more than €1,000/month and looking to scale
This is where Bleam truly shines. AI assistant negotiating and replying to buyers 24/7, listing templates speeding up publications, hourly automatic backup, labels ordered automatically. At that volume, every unhandled hour represents potentially lost sales.
Pro reseller with multiple Vinted accounts
At this level, Bleam is clearly the right fit. Multi-account on a single subscription with the inbox of all your accounts, Bleam Cloud to run the extension 24/7 with your computer off, the iPhone and Android app to steer everything from your phone, and the AI assistant multiplying sales on each account in parallel. The gains massively outweigh the subscription cost.

Domande frequenti
Clemz or Bleam to start on Vinted?
Bleam. You get features Clemz doesn't have: listing templates, full hourly backup, scheduled reposting, automatic label ordering, the inbox of all your accounts and the iPhone and Android app. To start out and save time right away, with a 14-day free trial, it's the most direct choice.
What's the best alternative to Clemz in 2026?
Bleam is today the most complete alternative to Clemz: scheduled reposting, favorite messages with rules and offers, plus listing templates, the AI assistant with its Memory, full hourly backup, automatic label ordering, the inbox of all your accounts and the iPhone and Android app.
Can I use Clemz and Bleam at the same time?
Technically yes, but honestly there's no point. You'll duplicate actions (two sets of favorite messages for instance) and stacking two automation tools on the same account increases the risk that Vinted detects unusual behavior. Pick one tool.
How to migrate from Clemz to Bleam?
Nothing to migrate, each extension is independent. Uninstall Clemz, install Bleam from the Chrome Web Store, log in, done. Your Vinted listings aren't affected.
Does Bleam offer features that Clemz doesn't have?
Yes, several. Listing templates (to post your items in 30 seconds), automatic backup of all your listings every hour, labels automatically ordered the moment a sale happens, the AI assistant that negotiates and replies to buyers, Bleam Cloud to run the extension 24/7 with your computer off, multi-account Vinted on a single subscription with the inbox of all your accounts, the iPhone and Android app and Lifecycle, which lowers the price of items that aren't selling on its own.
What does Bleam's AI assistant do?
It answers buyers' questions (size, material, shipping) and negotiates offers 24/7 based on your margins, never going below your floor price. With its Memory, it reuses the answers you teach it, and with Bleam Cloud it keeps going with your computer off. Clemz negotiates with rules but has no AI replies (checked on October 20, 2026).
Does Bleam work on multiple Vinted accounts at once?
Yes, up to 35 accounts depending on your subscription. Link your Vinted accounts to your Bleam account, every automation runs in parallel on each one and the centralized inbox brings their conversations together, with a single subscription.
How long does setup take?
5 to 10 minutes. Install the extension, connect your Vinted account, set your preferences (favorite messages, negotiation margins if you enable the Assistant), and you're good. The UI is designed to take 2 minutes, not 2 hours.
Any risk of a Vinted ban?
The risk is low. Bleam does for you what you'd do by hand (sending messages, relisting items), spacing out its actions to stay within Vinted's limits, and it doesn't change how the site works. No tool can promise zero risk, but over 10,000 sellers use Bleam every day.
